Vacuum-assisted vegetation removal with percutaneous lead extraction: a systematic review of the literature.

Abstract

To perform a systematic review of reports in which the AngioVac™ percutaneous vacuum-assisted aspiration system was successfully used to debulk or remove vegetations prior to percutaneous lead extraction. We included all studies and case reports that used a percutaneous aspiration technique for vegetation removal or debulking with percutaneous lead extraction for patients with lead-associated endocarditis. Ten reports and retrospective data from our centers were used, which included a total of 88 patients and 205 leads. The percutaneous aspiration procedure was completely or partially successful in 86 patients (97.7%). The lead extraction procedure itself was successful in 87 patients (98.9%). The aspiration procedure and lead extraction were done concomitantly in 81 patients (92.0%). Four patients (4.5%) had major complications (two due to vascular injuries, one due to coronary sinus injury, and one due to tricuspid valve injury). There were no complications from the aspiration procedure, and no cases were associated with procedure-related mortality. While patients with large vegetations have historically been referred for surgical lead extraction, data are lacking in its techniques and outcomes. Existing data suggest that percutaneous vacuum-assisted aspiration for vegetation removal or debulking in endocarditis prior to or concurrent with percutaneous lead extraction has a high success rate with a low complication rate across a broad series of patients.
